Room Temperature Photon Detectors
Room Temperature Photon Detectors provides an overview of the performance of emerging new generation of room temperature photodetectors generally called low-dimensional solid (LDS) photodetectors among which the most important are two-dimensional (2D) materials, perovskites, and quantum dots (QDs)/nanowires (NWs) operating in a wide spectral range from the ultraviolet (UV), visible (VIS), far infrared (FIR) to terahertz (THz). The LDS reported performance at room temperature is even better than that presented for standard commercial photodetectors. This book describes the peculiarities of the physical properties of LDS materials and their impact on the photodetectors’ performance. It also undertakes a comprehensive analysis of these performances when confronted with the standard photodetectors dominating the global market. Currently, intensive efforts are being made to reduce the cost of imaging systems and, in particular in the infrared (IR) range, to increase their operating temperature by reducing size, weight and power consumption (SWaP). This raises the question of whether the emergence of a new generation of LDS photodetectors will result in their rapid commercialization and serious competition for the standardized bulk photodetectors. This book attempts to answer those issues/questions. Features • Defines the importance of LDS photodetectors in the broad group of standard UV, VIS, IR, and THz photodetectors, and includes their advantages/disadvantages • Covers different types of photodetectors, including the relevant aspects of theory, types of materials, their physical properties, and detector fabrication • Provides invaluable resource for graduate students in physics and engineering, as well as a guide for those already working with sensors and systems, thermal imaging, remote sensing, optical telecommunications, and light detection.
Low Energy Photon Detection
This thesis showcases innovative new approaches aimed at advancing the next generation of long wave infrared (LWIR) light detectors and cameras. Detecting LWIR light at room temperature has posed a persistent challenge due to the low energy of photons. The pursuit of an affordable, high-performance LWIR camera capable of room temperature detection has spanned several decades. The two approaches detailed within are designed to offer high detectivity, swift response times, and room temperature operation. The first involves harnessing the Dirac plasmon and the Seebeck effect in graphene to create a photo-thermoelectric detector. The second entails the use of an oscillating circuit integrated with phase change materials and the modulation of frequency induced by infrared illumination to achieve LWIR detection. Finally, the graphene-based detectors are integrated with readout circuits to enable the development of a dense pixel focal plane which has strong potential for commercialization. The journey from novel material to device to functional camera presented here is essential reading for researchers in the field of photon detection.
